VSP 7200 v VSP7400?

[jwumcp]

Can I have someone here explain to me what the major difference between VSP7200 and VSP7400? I am going to buy an aggregation switch, some ERS5900 switches will be connected to it. I was debating which VSP switch I should buy. It is a small site with less than 200 users.

Thank you,

John

Correct, however only the VSP7200XTQ had MACsec on the copper ports only.  Not on the 40GE ports.

The VSP7200XSQ has no MACsec.

vsb7400 has no phy-chips, so you can’t use MACSEC.

If you need MACSEC you need to use the older vsb7200 or a bigger 8k device

Thank you all for the information provided here.

@Jay2009 you will have to clarify what you mean by XA 1400 features on the 7400 because the reality is the other way around i.e. XA 1400 supports a sub-set of the features supported on VSP 7400. Two exceptions are Fragmentation and Reassembly with Fabric Extend tunnels and IPsec with Fabric Extend Tunnels which are currently supported on XA 1400 only.

The reason XA 1400 can support Fragmentation and Reassembly is because the dataplane is software based unlike all the other VSP switches where the dataplane is hardware based and the switching ASICs used do not support fragmentation and reassembly natively. 

As far as IPsec with Fabric Extend Tunnels goes, please reach out to your AE/SE for a roadmap update.
